REPRESENTATION OF WIND ENERGY GENERATION´S UNCERTAINTIES IN THE STUDIES OF ELECTRICAL OPERATION´S PLANNING AND SAFETY ANALYSIS

Abstract

The search for alternative sources of clean energy which are capable of substituting polluting sources , seeking the reduction of environmental damage, has resulted in the growth of wind power sources. This type of energy source utilizes massives wind turbines in order to convert the air masses' kinetic energy into electrical energy. However, intrensic variations to the wind´s velocity , as well as the intermittence related to this power source might culminate in both economic and social problems, as a result of voltage instability. Under this perspective, this written paper has as main objective the presentation of a methodology to represent the uncertainties in this generation model, focusing on the short term electric tension stability analysis. In this project, the understanding of how different parameters affect wind´s velocity in specific regions is among its main goals. Therefore, the data collected in weather stations will be analyzed for this purpose. Moreover, a statistic method is going to be elaborated, with the intention to obtain parameterizations to estimate the wind´s velocity as a function of time, in a given period. Nevertheless, the goal is to obtain a model which will be helpful in the electrical operation´s planning and safety analysis of electrical power systems with a considerable participation of wind energy generation sources.
